Product Description
Stanford Microdevices’ SCA-6 is a high performance Gallium
Arsenide Hetrojunction Bipolar Transistor MMIC Amplifier. A
Darlington configuration is utilized for broadband perfor-
mance up to 3 GHz. The heterojunction increases break-
down voltage and minimizes leakage current between
junctions. Cancellation of emitter junction non-linearities
results in higher suppression of intermodulation products.
Typical IP3 at 50mA is +30dBm.
SCA-6
DC-3 GHz, Cascadable
GaAs HBT MMIC Amplifier
These unconditionally stable amplifiers provides 15dB of gain
and +14.5dBm of 1dB compressed power and requires only
a single positive voltage supply. Only 2 DC-blocking capaci-
tors, a bias resistor and an optional inductor are needed for
operation.
This MMIC is an ideal choice for wireless applications such
as cellular, PCS, CDPD, wireless data and SONET.
